Do I need a permit for plumbing fixture or repiping in Cary?
Yes. In North Carolina, plumbing fixture or repiping generally requires a permit, and Cary is no exception.
Repiping a home is plumbing work and requires a permit; it is never covered by the NCGS 160D-1110 minor-work exemption regardless of cost. If walls are opened and re-closed, the framing patch and insulation may need to be inspected before cover; confirm the inspection sequence with your local department. The Town of Cary requires a permit to add or relocate plumbing components such as water lines and sewer lines, and water and sewer line replacements (including replacing poly piping with PEX) are available as an Administrative Trades Permit through Building Permits Online. Replacement of plumbing fixtures is exempt only when the work does not change the design or capacity and does not go beyond the trap seal, so a whole-house repipe is not covered by that exemption. A homeowner may permit and do their own plumbing work, but state law requires the property to remain the owner's primary residence for at least 12 months after the work is completed. Wake County's own permitting office is Wake County Permits and Inspections. It issues permits for the unincorporated county, and in North Carolina the county is often the building authority even inside city limits, so confirm which applies to your address. Plumbing work is an express exception to the $40,000 exemption, so a repipe needs a permit regardless of cost.
